The Sun
- the photosphere (the visible surface of the Sun),
- the chromosphere (an irregular layer above the photosphere where the temperature rises from 6000°C to about 20,000°C),
- a transition region (a thin and very irregular layer of the Sun's atmosphere that separates the hot corona from the much cooler chromosphere),
- and the corona (the Sun's outer atmosphere.). ...
Which layer of the Sun do we normally see?
Which layer of the sun do we normally see with our unaided eye? The outermost layer of the Sun's atmosphere, the corona, can only be seen with the naked eye during a total solar eclipse. Then, the light from the photosphere is fully masked by the Moon.
What is the outer most layer of the Sun called?
The outermost layer of the Sun is called the corona or the crown. The corona is very thin and faint and is therefore very difficult to observe from the earth. … The corona also emits energy of many different wavelengths, from long wavelength radio waves, to short wavelength X-rays.
What is the innermost layer of the Sun?
There are three inner layers of the Sun, and the Convection zone is the outermost one. It completely surrounds the next layer, the Radiative zone, after which we have the Core, as the innermost layer of the Sun. Just like our planet, and most other celestial bodies, the Sun is divided into distinct layers.
Which layer of the Sun is the hottest?
The hottest part of the Sun is the core, at 28,080,000°F, on average. Radiative Zone The second layer becomes cooler and is where photon particles carry energy in all directions through a process called radiation.

How long does it take for a photon to travel through the Sun?
Photons travel through the radiative zone, and they can’t travel through long ranges of space, so it takes almost 50 million years for a photon to travel through this layer of the Sun.

The only layers of the Sun that can be observed directly are the outer layers: photosphere, chromosphere, and corona. These three layers make up the solar atmosphere.
What is the core of the Sun?
The core of the solar Sun is the layer where nuclear fusion reactions are generated. Therefore, it is where all the energy is generated. It is composed of gas that appears as a plasma due to high temperature (about 15 million degrees Celsius) and pressure due to its own magnetic field. High pressure is necessary for nuclear fusion to occur.
Why do sunspots appear?
In the photosphere, sunspots (7) are formed, which are dark spots on the solar surface due to their much lower temperature. Most solar flares (9) appear around sun spots.
How is the Sun represented?
The structure of the Sun is represented in different spherical layers difficult to determine with a physical boundary.
How wide is the chromosphere?

What is the sun made of?
The sun is made of several complex layers, each with its own unique job that ultimately produces energy. This energy controls the Earth’s climate and weather and provides life for all living things on earth.
How much heat does the Sun get from the core?
The heat from the core is 15 million degrees Kelvin which translates to roughly 27 million degrees Fahrenheit. Kelvin is a temperature scale that picks up where the Celsius degree ends. The core is comprised of a radiative layer that emits radiation and a convective layer that transfers heat. The heat inside the core causes protons and electrons to rub together creating an energy source for the Sun.

The Radiation Zone. The radiation zone is just outside the core. The function of this layer is to transfer energy from the core to the other layers. The temperature at this layer is cooler than the core at 7 million degrees Fahrenheit causing thermal radiation. This layer has 60 percent mass and 90 percent volume.

What is the third and final region of the solar interior?
The third and final region of the solar interior is named the convective (or convection) zone.
